Description
Technical Field
The invention relates to the field of expansive soil slope protection, in particular to a waterproof energy dissipation supporting structure for an expansive soil slope.

In order to solve the waterproof problem, there are many methods at present, including driving engineering protection structures such as anchor rods, soil nails, anchor cables, anti-slide piles and retaining walls, and also including some new construction processes including changing the properties of soil or replacing and filling, etc. to solve or transfer and avoid the problem of water swelling of the swelling soil slope, so as to achieve the purpose of improving the slope stability, i.e. engineering reliability. There are still many problems, including high construction cost, complex construction process, high maintenance cost and low reliability. Although there are many utility models and patents that have at present and improve slope stability, still there are some not enough:

The device equipment has the characteristics of skillfully applying the waterproof material, but only simply utilizes the waterproof characteristic of the waterproof material, and does not change the form of the waterproof material, so that the waterproof material is more fully utilized to protect the whole structure of the equipment.
The invention discloses a self-adaptive expansive soil side slope expansion and contraction deformation anti-sliding structure with the publication number of CN202011435048.7 and an application method thereof, and discloses a method for realizing the expansion and contraction deformation of an adaptive deformation section of skull elastic support, so that the anti-sliding structure is scaled to adapt to the expansion and contraction deformation of an expansive rock-soil body, and the influence of the expansion and contraction deformation of the expansive rock-soil body on the anti-sliding structure and other side slope auxiliary structures is weakened. Although the patent of the invention effectively solves the problem of expansion and shrinkage of the expansive soil side slope, the waterproof characteristic of the expansive soil side slope is not solved, the stability of the side slope is improved to a certain extent, and the protection of a protection structure in the working process is not considered.
The invention discloses an assembly type anchor rod frame beam structure which is suitable for an expandable soil side slope and contains an EPS elastic cushion layer, and the invention is CN202010952558.5, the invention improves the construction efficiency and quality of the side slope supporting engineering by paving the EPS elastic cushion layer on two sides of a reinforced concrete concave beam prefabricated unit, the invention has certain common points on a waterproof material suitable for the expandable soil side slope and a construction process to some extent, but the invention mainly utilizes the elastic property of EPS and applies the waterproof characteristic (inferior) of the EPS plate to some extent, mainly considers the combination of the EPS material and a frame beam, does not consider changing the structural form of the EPS plate and fully utilizes the waterproof, moisture-proof and shock-absorbing characteristics to more effectively and economically use the material.
